High Third-Trimester Stress Levels Dip Boys’ IQ, Study Reveals

A pregnant woman's mental health and well-being play a crucial role in the development of her unborn child. A lot of scientific research in the field of prenatal health has been done thus far, and recently, a new groundbreaking study from Odense University Hospital in Denmark has given significant findings.

This study explained that high levels of stress faced by the mother during the third trimester may decrease the IQ of her unborn male child. This discovery is particularly essential since it says that stress levels may more adversely impact boys than girls.

Cortisol, also known as the "stress hormone," is this study's primary topic of discussion. It is released in reaction to stress and is very essential to the growth of a fetus. It affects a lot of physiological functions and may have an effect on the child's cognitive development later in life. It is interesting to note that cortisol levels rise naturally throughout the course of pregnancy, and these levels are more significant in women carrying female fetuses than those carrying male fetuses.

The Role of Cortisol in Fetal Development

In this study, 943 pregnant women in the third trimester had their cortisol and cortisone levels examined. These kids were tested for IQ when they turned seven years old. The outcomes were very instructive. On IQ tests, boys whose moms had more significant amounts of cortisol in the womb performed worse. Conversely, girls with mothers with greater urine levels of the cortisone hormone (associated with cortisol) did better on the tests.

The study's lead author, Dr. Anja Fenger Dreyer, explained these variations in gender. She proposed that 11β-hydroxysteroid-dehydrogenase type 2 (11β-HSD2), an enzyme found in the placenta, may provide some shielding to female babies from their mothers' cortisol. However, male fetuses may be more susceptible to this hormone.

On the other hand, it is astonishing that the same team of experts recorded that, in the third trimester of gestation, children with advanced vocal and language technique qualities throughout the periods of one and three years presented indications of elevated cortisol. This suggests that the impact of prenatal cortisol exposure may vary at different stages of development and may have different effects on boys and girls.

Stress Management's Significance During Pregnancy

The study's findings emphasize the importance of reducing stress when pregnant, particularly in the third trimester. High levels of stress during this period may negatively impact the cognitive development of male youngsters for some time. To ensure that their unborn child develops normally, expectant moms need to learn effective stress management techniques and seek assistance.

This study also emphasizes the necessity of more research to fully comprehend the intricate connection between cortisol levels, mother stress, and child development. As these links become clearer, we will be able to more efficiently support expectant mothers and encourage children's healthy cognitive development.

In a nutshell, this study offers insightful information about how maternal stress affects children's cognitive development. It highlights the significance of stress management during pregnancy and the demand for additional studies in this field. The results also suggest that there may be gender variations in the impacts of prenatal stress, which emphasizes the need for individualized approaches to prenatal care and the development of young children. So, let's ensure our soon-to-be mothers and their children have the best start in life by caring for them. A happy family is built on the foundation of a healthy mother and a healthy child, after all.
